Nutrition Calculator

Nutrient calculators add macronutrients of each diet by weight, giving the total amount of home-made meals that cannot be covered by packaging labels.

Accuracy depends on the right weight and the right database entry; brands differ from fresh forms of calorie per gram.

Energy calculations used **Atwater coefficient**: carbon water 4 kcal/g, protein 4 kcal/g, fat 9 kcal/g (alcohol 7 kcal/g but no nutritional value). So ** the energy density of fat is 2.25 times that of carbon water and protein** — that's why it's about 10 g cooking oil (about a spoon) = 90 kcal, while 10 g rice is about 12 kcal. ** Recommended in the food guide for the Chinese population: Adult males of about 2,250 kcal/day and females of about 1,800 kcal/day** (light physical activity), depending on age, weight and activity.

** The core of the weight reduction is the caloric shortfall, but not below base metabolism**. Basic metabolic rate (BMR) can be estimated using the Mifflin-St Jeor formula: Men BMR = 10 x body weight (kg) + 6.25 x height (cm) - 5 x age + 5; Women = 10 x body weight + 6.25 x height - 5 x age - 161. For example, men aged 30, 70 kg, 175 cm: BMR ≈ 1,647 kcal, multiplied by the activity factor (sitting 1.2, light activity 1.375, medium 1.55), are required to consume the total daily consumption. **The daily gap recommended for lipid reduction is 300-500 kcal, corresponding to a weekly weight reduction of approximately 0.3-0.5 kg** - This is a sustainable rate, and the gap over the General Assembly has led to a reduction in metabolism and muscle loss, which is highly resilient.
